Intuition behind $\nabla \times \mathbf{F}$I remember him doing just the opposite, something about drawing crystal tubes in a fluid and seeing what it happened to the fluid int he tube and how it's related to the curl.

Intuition behind $\nabla \times \mathbf{F}$A really good intuitive explanation is the one Feynman gives in the first chapters of his second volume of "Lectures in Physics". The first two chapters are about vector calculus, and he explains this stuff really good.

How to win a game like this?@MichaelGreinecker I honestly haven't studied game theory very formally... Then the 0 is the Nash equilibrium of the game, isn't it? The state in which no player will want to change strategy?
